Should the Blue Jays Promote Trey Yesavage for His MLB Debut This Season?

Trey Yesavage has rapidly advanced through the Blue Jays' system in his first pro season. After his promotion to Triple-A Buffalo was reported on August 11, MiLB.com ranked him the organization's new No. 1 prospect.

Yesavage excelled in college. In 2023 and 2024 at East Carolina University, the righty posted 2.61 and 2.03 ERAs, with 105:29 and 145:36 strikeout-to-walk ratios. The Blue Jays appear to have gotten a steal with the 20th pick in the 2024 draft; MLB.com had ranked him 11th in the class.

The fireballer has been able to bring his strong college performances to the Blue Jays' farm system. In his first professional season, he's pitched at Single A, High A, and Double A. At those three levels combined over 80 2/3 innings, Yesavage has posted a 3.01 ERA and a 134:31 strikeout-to-walk ratio. He has held batters to a .160 batting average off him. However, his ERA is heavily skewed by his success in Dunedin and Vancouver, where he had 2.43 and 1.05 ERAs, respectively, over 50 2/3 innings. The 22-year-old struggled a bit more over 30 innings with New Hampshire, posting a 4.50 ERA, although his strikeout-to-walk ratio (46:11) was still excellent, and he held batters to a .198 batting average.

Despite the high ERA in Double A, Yesavage showed flashes of massive potential and earned his promotion to Triple-A Buffalo. The Blue Jays have done a good job managing the phenom's workload, limiting him to four or five innings at most and 70-75 pitches for all but one game in his first minor league season. He did throw 89 pitches out of the bullpen in his last outing, over five innings, but that may be a sign of the Blue Jays ramping up his workload for his last few outings after he was limited for most of the season.

The Blue Jays now find themselves with a tricky decision to make: give Yesavage a September call-up or wait until next season to let him make his MLB debut. The team is leading the AL East by 4.5 games as of August 11. The Boston Red Sox, currently in second place, experienced a surge at the end of July and the beginning of August, posting a 10-3 record before losing their last three games. The Blue Jays also have to hold off the New York Yankees, who trail by six games, though they are 3-7 in their previous 10.

The Blue Jays have the eighth toughest schedule over the rest of the season (per Tankathon), with three games against each of the Red Sox and Yankees amongst their 43 remaining games. Boston and New York have the ninth and fourth easiest schedules, respectively. With the pressures of the fight to win the AL East down the stretch, the Blue Jays may feel the need to bring Yesavage up. The decision will be determined by whether they believe they've managed the righty's workload properly and, therefore, if he has innings left in him. This is the time in the season when teams start to weigh the decision of easing their young pitchers' workloads to ensure they stay healthy for the future.

Yesavage's highest single-season innings total in college was 93 1/3 in his last year at ECU. The fact that his last appearance at Double A was a bullpen outing could indicate that the Blue Jays are seeing how he performs in a relief role, because if he's called up, that will likely be his job. The starting rotation is set, barring injuries, with José Berríos , Kevin Gausman, Max Scherzer, Chris Bassitt, and Eric Lauer. Shane Bieber was acquired from the Cleveland Guardians ahead of the trade deadline with the hopes he'd be available towards the end of the season after recovering from Tommy John surgery. Alek Manoah and Bowden Francis are two more possible starters if they can progress through their respective injury rehabs soon enough.

Pitching Yesavage out of the bullpen could be a way to further manage his workload, but the question is, with him 13 innings from his career-high, is it smart for the Jays to extend the 22-year-old and the future of the franchise? He'll likely be competing for a starting role next spring, so it's tempting to give him experience at the highest level.

It's a tough decision, but if Yesavage continues to impress in his next couple of outings, and the AL East race gets tighter, the Blue Jays' hands may be forced to bring up their young prospect for some relief.
